To all whom it may concern Be it known tha-t i zen of the UnitedStates,'residing in the city and county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Tooth-Brushes,of which the following is a specification.

This invention rela-tes to tooth brushes.

It is an object ofthe presentinvention to provide an improved toothbrush of collapsible structure in combination with a co'vering case.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which Figure l is alongitudinal section of the Fig. 2 /i a longitudinal section of thecollapsed b1 ish. Fig. 3 is a cross section on' line 3-3 of Fig. 2.

'Ihe present device includes a part Q, in which are suitably secured thebrush bristles 3, and is provided'with a shank `portion 4, of taperingconfiguration, increasing in diameter toward its end. This shank porltion e is telescopic Within a frusto-conoidal. tubular handle section 5,the larger end of which telescopically fits andengages the shell or-end6, which serves not onl7 the purpose of a handle for the extended brush.when ready for use, but also serves as a portion ofthe cover or casingfor the brush parts, when telescoped as shown in Fig. 2. i

Theitelescopic parts 1l, 5 and 6 are designed for coaction, whendistended, to forni a substantial lhandle for the manipulation of thebrush, and when the telescopic sections are contracted, as shown in Fig.2. the bristle or head end of the brush, which pro- -jeots from theshell section G, is covered b,v a

cap 7 fitting over the adjacent end of the shell 6, said cap having ahollow' head portion, which opens into an vintegral trough of lessdiameter than the head, the side walls of the trough serving to preventspreading of the bristles when the brush head is positionedin the headportion.

The shell or cover is preferabh7 of oblong cross section so as tooccup)7 as small a .space as possible and so that it may be readilvinserted in the vestv or other pocket and lie in a flat position. V

Having thus described inv invention.l what I claim and desire to securebv Letters Patent is i l. A tooth brush comprising a bristle head partwith a tapering and curved shank. an intermediate tubular taperinghandle section cooperating with said shank, when extended. to hold thelatter. a tubular end section or shell coperating with the intermediatesection, when extended, to hold the latter. said sections being disposedin angular relation to said shank, said sections and shank beingtelescopic, and a cap for covering the bristle end of the brushextending from the tele scoped parts.
